The Lord God is my Strength, my personal bravery, and my invincible army; He makes my feet like hinds’ feet and will make me to walk [not to stand still in terror, but to walk] and make [spiritual] progress upon my high places [of trouble, suffering, or responsibility]!
Habakkuk 3:19 AMP
When you are low on strength, what a promise to remember!
Do you not know? Have you not heard? The Lord is the everlasting God,the Creator of the ends of the earth. He will not grow tired or weary, and His understanding no one can fathom.
He gives strength to the weary and increases the power of the weak. Even youths grow tired and weary, and young men stumble and fall; but those who hope in the Lord will renew their strength. They will soar on wings like eagles; they will run and not grow weary, they will walk and not be faint. – Isaiah 40:28-31 NIV

For the sake of Christ, then, I am content with weaknesses, insults, hardships, persecutions, and calamities. For when I am weak, then I am strong. – 2 Cor 12:9-10
